Synthetic, man-made cells and ultrathin electronics built from a new form of “zero-dimensional” carbon nanotube may be possible through research at the University of Pittsburgh Swanson School of Engineering.
“Since its discovery, carbon nanotubes have held the promise to revolutionize the field of electronics, material science and even medicine,” said Steven R. Little, PhD, associate professor, CNG Faculty Fellow and Chair of the Department of Chemical and Petroleum Engineering, a principal investigator. “Zero-dimensional carbon nanotubes present the possibility to build ultrathin, superfast electronic devices, far superior to the best existing ones and it could be possible to build strong and ultralight cars, bridges, and airplanes.”
One of the most difficult hurdles is processing the carbon nanotubes into smaller forms. However, previous research at Pitt has managed to cut the carbon nanotubes into the smallest dimensions ever to overcome this problem.
The new research-paper explaining thei break-through, ““Zero-Dimensional” Single-Walled Carbon Nanotubes,” was recently published in the journal Angewandte Chemie.
“We have confirmed that these shorter nanotubes are more dispersible and potentially easier to process for industrial as well as biomedical application, and could even constitute the building blocks for the creation of synthetic cells,” says Dr. Riccardo Gottardi, a co-investigator.
The organization of the atoms within nanotubes makes them particularly interesting materials to work with. However, they are barely soluble, making industrial processing difficult. One aspect of the team’s research will focus on creating more soluble and therefore more usable carbon nanotubes. These shorter nanotubes have the same dimensions as many proteins that compose the basic machinery of living cells, presenting the potential for cell or protein-level biomedical imaging, protein or nucleic acid vaccination carriers, drug delivery vehicles, or even components of synthetic cells.
Overall, the project is aimed at developing and working with these more dispersible carbon nanotubes with the aim of making them easier to process. The creation of the smaller nanotubes is the first step toward reaching this goal. -- Source: University of Pittsburgh
